Guidelines for trained service technicians

This section contains information for trained service technicians.

Inspecting for unsafe conditions

Use the information in this section to help you identify potential unsafe conditions in an IBM product that you are working on. Each IBM product, as it was designed and manufactured, has required safety items to protect users and service technicians from injury. The information in this section addresses only those items. Use good judgment to identify potential unsafe conditions that might be caused by non-IBM alterations or attachment of non-IBM features or options that are not addressed in this section. If you identify an unsafe condition, you must determine how serious the hazard is and whether you must correct the problem before you work on the product.

Consider the following conditions and the safety hazards that they present:

v Electrical hazards, especially primary power. Primary voltage on the frame can

cause serious or fatal electrical shock.

v Explosive hazards, such as a damaged CRT face or a bulging capacitor.

v Mechanical hazards, such as loose or missing hardware.

inspect the product for potential unsafe conditions, complete the following steps:

1. Make sure that the power is off and the power cord is disconnected.

2. Make sure that the exterior cover is not damaged, loose, or broken, and observe any sharp edges.

3. Check the power cord:

v Make sure that the third-wire ground connector is in good condition. Use a

meter to measure third-wire ground continuity for 0.1 ohm or less between the external ground pin and the frame ground.

v Make sure that the power cord is the correct type, as specified in “Power

cords” on page 95.

v Make sure that the insulation is not frayed or worn.

Remove the cover.

5. Check for any obvious non-IBM alterations. Use good judgment as to the safety of any non-IBM alterations.

6. Check inside the server for any obvious unsafe conditions, such as metal filings, contamination, water or other liquid, or signs of fire or smoke damage.

7. Check for worn, frayed, or pinched cables.

8. Make sure that the power-supply cover fasteners (screws or rivets) have not been removed or tampered with.

Guidelines for servicing electrical equipment

Observe the following guidelines when servicing electrical equipment:

v Check the area for electrical hazards such as moist floors, nongrounded power

extension cords, power surges, and missing safety grounds.

v Use only approved tools and test equipment. Some hand tools have handles that

are covered with a soft material that does not provide insulation from live electrical currents.

v Regularly inspect and maintain your electrical hand tools for safe operational

condition. Do not use worn or broken tools or testers.

viii IBM xSeries 460 Type 8872 and xSeries MXE 460 Type 8874: Problem Determination and Service Guide

v Do not touch the reflective surface of a dental mirror to a live electrical circuit.

The surface is conductive and can cause personal injury or equipment damage if it touches a live electrical circuit.

v Some rubber floor mats contain small conductive fibers to decrease electrostatic

discharge. Do not use this type of mat to protect yourself from electrical shock.

v Do not work alone under hazardous conditions or near equipment that has

hazardous voltages.

v Locate the emergency power-off (EPO) switch, disconnecting switch, or electrical

outlet so that you can turn off the power quickly in the event of an electrical accident.

v Disconnect all power before you perform a mechanical inspection, work near

power supplies, or remove or install main units.

v Before you work on the equipment, disconnect the power cord. If you cannot

disconnect the power cord, have the customer power-off the wall box that supplies power to the equipment and lock the wall box in the off position.

v Never assume that power has been disconnected from a circuit. Check it to

make sure that it has been disconnected.

v If you have to work on equipment that has exposed electrical circuits, observe

the following precautions:

– Make sure that another person who is familiar with the power-off controls is

near you and is available to turn off the power if necessary.

– When you are working with powered-on electrical equipment, use only one

hand. Keep the other hand in your pocket or behind your back to avoid creating a complete circuit that could cause an electrical shock.

– When using a tester, set the controls correctly and use the approved probe

leads and accessories for that tester.

– Stand on a suitable rubber mat to insulate you from grounds such as metal

floor strips and equipment frames.

Use extreme care when measuring high voltages.

v To ensure proper grounding of components such as power supplies, pumps,

blowers, fans, and motor generators, do not service these components outside of their normal operating locations.

v If an electrical accident occurs, use caution, turn off the power, and send another

person to get medical aid.

Chapter 2. Diagnostics

This chapter describes the diagnostic tools that are available to help you solve problems that might occur in the server.

If you cannot locate and correct the problem using the information in this chapter, see Appendix A, “Getting help and technical assistance,” on page 143 for more information.

Diagnostic tools

The following tools are available to help you diagnose and solve hardware-related problems:

v POST beep codes, error messages, and error logs

The power-on self-test (POST) generates beep codes and messages to indicate successful test completion or the detection of a problem. See “POST” for more information.

v Troubleshooting tables

These tables list problem symptoms and actions to correct the problems. See “Troubleshooting tables” on page 36.

v Light path diagnostics

Use light path diagnostics to diagnose system errors quickly. See “Light path diagnostics” on page 49 for more information.

v Diagnostic programs, messages, and error messages

The diagnostic programs are the primary method of testing the major components of the server. The diagnostic programs are in read-only memory on the server. See “Diagnostic programs, messages, and error codes” on page 59 for more information.

v Real Time Diagnostics

Real Time Diagnostics can help you diagnose problems in certain devices while the operating system is running, to prevent or minimize server downtime. See “Real Time Diagnostics” on page 77 for more information.

POST

When you turn on the server, it performs a series of tests to check the operation of the server components and some optional devices in the server. This series of tests is called the power-on self-test, or POST.

If a power-on password is set, you must type the password and press Enter, when prompted, for POST to run.

If POST is completed without detecting any problems, a single beep sounds, and the server startup is completed.

If POST detects a problem, more than one beep might sound, or an error message is displayed. See “Beep code descriptions” on page 14 and “POST error codes” on page 20 for more information.

POST beep codes

A beep code is a combination of short or long beeps or series of short beeps that are separated by pauses. For example, a “1-2-3” beep code is one short beep, a pause, two short beeps, and pause, and three short beeps. A beep code other than one beep indicates that POST has detected a problem. To determine the meaning of a beep code, see “Beep code descriptions.” If no beep code sounds, see “No-beep symptoms” on page 18.

Beep code descriptions

The following table describes the beep codes and suggested actions to correct the detected problems.

A single problem might cause more than one error message. When this occurs, correct the cause of the first error message. The other error messages usually will not occur the next time POST runs.

Exception: If there are multiple error codes or light path diagnostics LEDs that

indicate a microprocessor error, the error might be in a microprocessor or in a microprocessor socket. See “Microprocessor problems” on page 42 for information about diagnosing microprocessor problems.

v Follow the suggested actions in the order in which they are listed in the Action column until the problem

is solved.

v See Chapter 3, “Parts listing, Type 8872 and Type 8874,” on page 93 to determine which components are

customer replaceable units (CRU) and which components are field replaceable units (FRU).

Error logs

The POST error log contains the three most recent error codes and messages that were generated during POST. The BMC log and the system-error log contain messages that were generated during POST and all system status messages from the service processor.

The following illustration shows an example of a BMC log entry.

18 IBM xSeries 460 Type 8872 and xSeries MXE 460 Type 8874: Problem Determination and Service Guide

----------------------------------------------------------

BMC System Event Log

Get Next Entry Get Previous Entry Clear BMC SEL

Entry Number= 00005 / 00011 Record ID= 0005 Record Type= 02 Timestamp= 2005/01/25 16:15:17 Entry Details: Generator ID= 0020

Sensor Type= 04 Assertion Event Fan Threshold Lower Non-critical - going high

Sensor Number= 40 Event Direction/Type= 01

Event Data= 52 00 1A

The BMC log is limited in size. When the log is full, new entries will not overwrite existing entries; therefore, you must periodically clear the BMC log through the Configuration/Setup Utility program (the menu choices are described in the User’s Guide). When you are troubleshooting an error, be sure to clear the BMC log so that you can find current errors more easily.

Entries that are written to the BMC log during the early phase of POST show an incorrect date and time as the default time stamp; however, the date and time are corrected as POST continues.

Each BMC log entry appears on its own page. To display all the data for an entry, use the Up Arrow (↑) and Down Arrow (↓) keys or the Page Up and Page Down keys. To move from one entry to the next, select Get Next Entry or Get Previous Entry.

The log indicates an assertion event when an event has occurred. It indicates a deassertion event when the event is no longer occurring.

Some of the error codes and messages in the BMC log are abbreviated.

If you view the BMC log through the Web interface of the optional Remote Supervisor Adapter II SlimLine, the messages can be translated.

You can view the contents of the POST error log, the BMC log, and the system-error log from the Configuration/Setup Utility program. You can view the contents of the BMC log also from the diagnostic programs.

When you are troubleshooting PCI-X slots, note that the error logs report the PCI-X buses numerically. The numerical assignments vary depending on the configuration. You can check the assignments by running the Configuration/Setup Utility program (see the User’s Guide for more information).

Viewing error logs from the Configuration/Setup Utility program

For complete information about using the Configuration/Setup Utility program, see the User’s Guide.

Chapter 2. Diagnostics 33

Checkout procedure

The checkout procedure is the sequence of tasks that you should follow to diagnose a problem in the server.

About the checkout procedure

Before performing the checkout procedure for diagnosing hardware problems, review the following information:

v Read the safety information beginning on page vii.

v The diagnostic programs provide the primary methods of testing the major

components of the server, such as the I/O board, Ethernet controller, keyboard, mouse (pointing device), serial ports, and hard disk drives. You can also use them to test some external devices. If you are not sure whether a problem is caused by the hardware or by the software, you can use the diagnostic programs to confirm that the hardware is working correctly.

v When you run the diagnostic programs, a single problem might cause more than

one error message. When this happens, correct the cause of the first error message. The other error messages usually will not occur the next time you run the diagnostic programs.

Exception: If there are multiple error codes or light path diagnostics LEDs that

v Before running the diagnostic programs, you must determine whether the failing

server is part of a shared hard disk drive cluster (two or more servers sharing external storage devices). If it is part of a cluster, you can run all diagnostic programs except the ones that test the storage unit (that is, a hard disk drive in the storage unit) or the storage adapter that is attached to the storage unit. The failing server might be part of a cluster if any of the following conditions is true:

– You have identified the failing server as part of a cluster (two or more servers

sharing external storage devices).

– One or more external storage units are attached to the failing server and at

least one of the attached storage units is also attached to another server or unidentifiable device.

– One or more servers are located near the failing server.

Important:

at a time. Do not run any suite of tests, such as “quick” or “normal” tests, because this might enable the hard disk drive diagnostic tests.

v If the server is halted and a POST error code is displayed, see “Error logs” on

page 18. If the server is halted and no error message is displayed, see “Troubleshooting tables” on page 36 and “Solving undetermined problems” on page 90.

v For information about power-supply problems, see “Solving power problems” on

page 88 and “Power-supply LEDs” on page 57.

v For intermittent problems, check the error log; see “Error logs” on page 18 and

“Diagnostic programs, messages, and error codes” on page 59.

If the server is part of a shared hard disk drive cluster, run one test

Performing the checkout procedure

To perform the checkout procedure, complete the following steps:

1. Is the server part of a cluster?

v No: Go to step 2.

v Yes: Shut down all failing servers that are related to the cluster. Go to step 2.

2. Complete the following steps:

a. Turn off the server and all external devices.

b. Check all cables and power cords.

c. Set all display controls to the middle positions.

d. Turn on all external devices.

e. Turn on the server. If the server does not start, see “Troubleshooting tables”

on page 36.

f. Check the system-error LED on the operator information panel. If it is

flashing, check the light path diagnostics LEDs (see “Light path diagnostics” on page 49).

g. Check for the following results:

v Successful completion of POST, indicated by a single beep

v Successful completion of startup, indicated by a readable display of the

operating-system desktop

Did a single beep sound and are there readable instructions on the main menu?

v No: Find the failure symptom in “Troubleshooting tables” on page 36; if

necessary, see “Solving undetermined problems” on page 90.

v Yes: Run the diagnostic programs (see “Running the diagnostic programs” on

page 59).

– If you receive an error, see “Diagnostic error codes” on page 60.

Checkpoint codes (trained service technicians only)

A checkpoint code identifies the check that was occurring when the server stopped; it does not provide error codes or suggest replacement components. Checkpoint codes are shown on the checkpoint display, which is on the I/O board. By using the checkpoint display, you do not have to wait for the video to initialize each time you restart the server.

There are two types of checkpoint codes: CPLD hardware checkpoint codes and BIOS checkpoint codes. The BIOS checkpoint codes might change when the BIOS code is updated.

For a list of checkpoint codes for the xSeries 460 or MXE 460 server, see http://w3.pc.ibm.com/helpcenter/infotips/techinfo/MIGR-58350.html.

Light path diagnostics is a system of LEDs on various external and internal components of the server. When an error occurs, LEDs are lit throughout the server. By viewing the LEDs in a particular order, you can often identify the source of the error.

The server is designed so that LEDs remain lit when the server is connected to an ac power source but is not turned on, provided that the power supply is operating correctly. This feature helps you to isolate the problem when the operating system is shut down.

Any PCI-X, memory, microprocessor, and VRM LED can be lit again without ac power after you remove the microprocessor tray so that you can isolate a problem. After ac power has been removed from the server, power remains available to these LEDs for up to 24 hours.

To view the PCI-X, memory, microprocessor, and VRM LEDs, press and hold the light-path-diagnostics button on the PCI-X board, memory card, or microprocessor board for 30 seconds to light the error LEDs.

The LEDs that were lit while the server was running will be lit again while the button is pressed.

Many errors are first indicated by a lit information LED or system-error LED on the operator information panel on the front of the server. If one or both of these LEDs are lit, one or more LEDs elsewhere in the server might also be lit and can direct you to the source of the error.

Chapter 2. Diagnostics 49

Before working inside the server to view light path diagnostics LEDs, read the safety information that begins on page vii and “Handling static-sensitive devices” on page 100.

If an error occurs, view the light path diagnostics LEDs in the following order:

1. Check the operator information panel on the front of the server.

v If the information LED is lit, it indicates that information about a suboptimal

condition in the server is available in the BMC log or in the system-error log.

v If the system-error LED is lit, it indicates that an error has occurred; go to

step 2.

The following illustration shows the operator information panel.

Look at the system service label on the top of the server, which gives an overview of internal components that correspond to the LEDs on the light path diagnostics panel. This information and the information in “Light path diagnostic LEDs” on page 52 can often provide enough information to correct the error.

3. Remove the server cover and look inside the server for lit LEDs. Certain components inside the server have LEDs that will be lit to indicate the location of a problem. For example, a VRM error will light the LED next to the failing VRM on the microprocessor tray.

The following illustration shows the LEDs and connectors on the microprocessor tray.

Diagnostic programs, messages, and error codes

The server diagnostic programs are the primary method of testing the major components of the server. As you run the diagnostic programs, text messages and error codes are displayed on the screen and are saved in the test log. A diagnostic text message or error code indicates that a problem has been detected; to determine what action you should take as a result of a message or error code, see the table in “Diagnostic error codes” on page 60.

Running the diagnostic programs

To run the diagnostic programs, complete the following steps:

1. If the server is running, turn off the server and all attached devices.

2. Turn on all attached devices; then, turn on the server.

3. When the prompt F2 for Diagnostics appears, press F2. If you have set both a

power-on password and an administrator password, you must type the administrator password to run the diagnostic programs.

4. From the top of the screen, select either Extended or Basic.

5. From the diagnostic programs screen, select the test that you want to run, and follow the instructions on the screen.

When you are diagnosing hard disk drives, select SCSI Fixed Disk Test for the most thorough test. Select Fixed Disk Test for any of the following situations:

v You want to run a faster test.

v The server contains RAID arrays.

v The server contains SATA or IDE hard disk drives.

To determine what action you should take as a result of a diagnostic text message or error code, see the table in “Diagnostic error codes” on page 60.

If the diagnostic programs do not detect any hardware errors but the problem remains during normal server operations, a software error might be the cause. If you suspect a software problem, see the information that comes with your software.

A single problem might cause more than one error message. When this happens, correct the cause of the first error message. The other error messages usually will not occur the next time you run the diagnostic programs.

Exception: If there are multiple error codes or light path diagnostics LEDs that

If the server stops during testing and you cannot continue, restart the server and try running the diagnostic programs again. If the problem remains, replace the component that was being tested when the server stopped.

The keyboard and mouse (pointing device) tests assume that a keyboard and mouse are attached to the server. If no mouse or a USB mouse is attached to the server, you cannot use the Next Cat and Prev Cat buttons to select categories. All other mouse-selectable functions are available through function keys. Yo u can use the regular keyboard test to test a USB keyboard, and you can use the regular mouse test to test a USB mouse. You can run the USB interface test only if no USB devices are attached. The USB test will not run if a Remote Supervisor Adapter II SlimLine is installed.

Chapter 2. Diagnostics 59

To view server configuration information (such as system configuration, memory contents, interrupt request (IRQ) use, direct memory access (DMA) use, device drivers, and so on), select Hardware Info from the top of the screen.

Diagnostic text messages

Diagnostic text messages are displayed while the tests are running. A diagnostic text message contains one of the following results:

Passed: The test was completed without any errors.

Failed: The test detected an error.

User Aborted: Yo u stopped the test before it was completed.

Not Applicable: Yo u attempted to test a device that is not present in the server.

Aborted: The test could not proceed because of the server configuration.

Warning: The test could not be run. There was no failure of the hardware that was

being tested, but there might be a hardware failure elsewhere, or another problem prevented the test from running; for example, there might be a configuration problem, or the hardware might be missing or is not being recognized.

The result is followed by an error code or other additional information about the error.

Viewing the test log

To view the test log when the tests are completed, select Utility from the top of the screen and then select View Test Log. The test-log data is maintained only while you are running the diagnostic programs. When you exit from the diagnostic programs, the test log is cleared.

To save the test log to a file on a diskette or to the hard disk, click Save Log on the diagnostic programs screen and specify a location and name for the saved log file.

Notes:

1. To create and use a diskette, you must add an optional external diskette drive to the server.

2. To save the test log to a diskette, you must use a diskette that you have formatted yourself; this function does not work with preformatted diskettes. If the diskette has sufficient space for the test log, the diskette can contain other data.

Diagnostic error codes

The following table describes the error codes that the diagnostic programs might generate and suggested actions to correct the detected problems.

If the diagnostic programs generate error codes that are not listed in the table, make sure that the latest levels of BIOS, Remote Supervisor Adapter II SlimLine, and ServeRAID code are installed.

In the error codes, x can be any numeral or letter. However, if the three-digit number in the central position of the code is 000, 195, or 197, do not replace a CRU or FRU. These numbers appearing in the central position of the code have the following meanings:

60 IBM xSeries 460 Type 8872 and xSeries MXE 460 Type 8874: Problem Determination and Service Guide

000 The server passed the test. Do not replace a CRU or FRU.

Real Time Diagnostics

Real Time Diagnostics can help you diagnose certain devices while the operating system is running, to prevent and minimize server downtime.

For more information and to download Real Time Diagnostics, go to: http://www-1.ibm.com/support/docview.wss?uid=psg1MIGR-50681.

Recovering from a BIOS update failure

The server has an advanced recovery feature that will automatically switch to a backup BIOS page if the BIOS code in the server has become damaged, such as from a power failure during an update.

The flash memory of the server consists of a primary page and a backup page. If the BIOS code in the primary page is damaged, the baseboard management controller will detect the error and automatically switch to the backup page to start the server. If this happens, a POST message Booted from backup POST/BIOS image is displayed. The backup page version might not be the same version as the primary page version.

You can then recover or restore the original primary page BIOS by using a BIOS flash diskette.

Note: To create and use a diskette, you must add an optional external diskette

drive to the server.

To recover the BIOS code and restore the server operation to the primary page, complete the following steps:

1. Download the latest version of the BIOS code from http://www.ibm.com/pc/support/.

2. Update the BIOS code, following the instructions that come with the update file that you downloaded. This will automatically restore and update the primary page.

3. Restart the server.

If that procedure fails, the server might not restart correctly or might not display video. To manually restore the BIOS code, complete the following steps:

1. Read the safety information that begins on page vii and “Handling static-sensitive devices” on page 100.

2. Turn off the server and peripheral devices and disconnect all external cables and power cords; then, remove the cover.

3. Locate the boot block recovery jumper (J14 on the I/O board) (see “I/O board internal connectors and jumpers” on page 8).

4. Disconnect the server from the ac power source.

5. Move the J14 jumper to pins 2 and 3 to enable the backup page.

6. Wait 30 seconds; then, connect the server to the ac power source.

7. Insert the BIOS flash diskette into the external diskette drive.

8. Restart the server.

9. When POST starts, select 1 - Update POST/BIOS from the menu that contains various flash (update) options.

10. When you are asked whether you want to save the current code to a diskette, type N.

Chapter 2. Diagnostics 77

11. Type 1 and press Enter to continue.

Attention: Do not restart or turn off the server until the update is completed.

12. When the update is completed, turn off the server.

13. Disconnect the server from the ac power source.

14. Move the J14 jumper back to pins 1 and 2 to return to startup from the primary page.

15. Wait 30 seconds; then, connect the server to the ac power source.

16. Replace the cover; then, restart the server.

System-error log messages

A system-error log is generated only if a Remote Supervisor Adapter II SlimLine is installed. The system-error log can contain messages of three types:

Information Information messages do not require action; they record significant

system-level events, such as when the server is started.

Warning Warning messages do not require immediate action; they indicate

possible problems, such as when the recommended maximum ambient temperature is exceeded.

Error Error messages might require action; they indicate system errors,

such as when a fan is not detected.

Each message contains date and time information, and it indicates the source of

the message (POST/BIOS or the service processor).

Note: The BMC log, which you can view through the Configuration/Setup Utility

program, also contains many information, error, and warning messages.

In the following example, the system-error log message indicates that the server was turned on at the recorded time.

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Date/Time: 2002/05/07 15:52:03 DMI Type: Source: SERVPROC Error Code: System Complex Powered Up Error Code: Error Data: Error Data:
